Rui:
Thanks. I will try it.
FYI: I did attached the data, but here it is re-attached.
Thanks, again.

Hello,
1) We don't have access to your file firstRdata.csv so what I'll say
is just an untested guess. You can post some of your data with the
following R command.
dput(head(Response, 20)) # paste the output of this in a mail
2) First you use read.csv that outputs a data.frame and then do
data.frame(Response). Useless. Response already is a df.
3) I believe the trouble you're facing comes from your use of
attach(). This function is _never_ needed and is cause of all sorts of
bugs. In particular, what you are ordering is the attached copy of
Response, and all changes you do to it will only have effect on the
copy. The original is left as it were.
So run the same code (with the obvious bug yhatResponse$yhat
corrected) but eliminating the 'attach' instruction. And see if it
reorders Response.
Hope this helps,
Rui Barradas
